There is a supplementary angle with a ratio of 3:7. What is the measure of the larger angle?

The measure of the bigger angle is 126 degrees

Step-by-step explanation:

When two angles are supplementary, the sum of the angles is 180

In the given ratio, the bigger angle is the one with 7

Thus;

7/(3 + 7) * 180 is the measure of the bigger angle

So;

7/10 * 180

= 7 * 18 = 126 degrees
